**Sat Feb 16, 2013 12:18**I'm getting so close to finishing my birch tree mod. PilzAdam, I used your rubber.lua from your farming mod to generate the trees, make the sapling, leaves, and sapling growth.

Here is the tree growth that seems to cause a problem when I add it to the code.
I get a ModError when I add this to the code. PS. The name of the mod is birch.

Here is the tree growth that seems to cause a problem when I add it to the code.

Code: Select all

```
llocal generate_birch_tree = function(pos)
node = {name = ""}
for dy=1,4 do
pos.y = pos.y+dy
if minetest.env:get_node(pos).name ~= "air" then
return
end
pos.y = pos.y-dy
end
node.name = "birch:tree"
for dy=0,4 do
pos.y = pos.y+dy
minetest.env:set_node(pos, node)
pos.y = pos.y-dy
end
node.name = "birch:leaves"
pos.y = pos.y+3
for dx=-2,2 do
for dz=-2,2 do
for dy=0,3 do
pos.x = pos.x+dx
pos.y = pos.y+dy
pos.z = pos.z+dz
if dx == 0 and dz == 0 and dy==3 then
if minetest.env:get_node(pos).name == "air" and math.random(1, 5) <= 4 then
minetest.env:set_node(pos, node)
end
elseif dx == 0 and dz == 0 and dy==4 then
if minetest.env:get_node(pos).name == "air" and math.random(1, 5) <= 4 then
minetest.env:set_node(pos, node)
end
elseif math.abs(dx) ~= 2 and math.abs(dz) ~= 2 then
